Chun-wei Fan 374a61f245 MSVC builds: Add scripts to generate .pc files
Add a generic script, pc_base.py, which can be utilized to obtain path
info, along with user-input version info, which can be used to generate
pkg-config .pc files.  Also enhance replace.py a bit so that it can also
be used in the future to replace multiple items in a file in one shot.
This is done to make building introspection files easier, as it depends
much on the pkg-config .pc files to work.

Update the project files so that when Python is available, we can generate
the full, usable .pc files when we complete and 'install' the builds, and
copy them to appropriate locations so that pkg-config can be set to find
them easily.

# Simple utility script to generate the basic info
# needed in a .pc (pkg-config) file, used especially
# for introspection purposes
# This can be used in various projects where
# there is the need to generate .pc files,
# and is copied from GLib's $(srcroot)/build/win32
